Harbor is a Tony Hawk's Pro Skater 1 level that only appeared in the GBC version. It is the fourth racing stage, and is a fairly basic level, just like every level in the GBC version. With trucks, forklifts, pipes, girders, boxes, water hazards, ramps and buildings, this level is what it says; a harbor, nothing more. Picture the area of the Merryweather Heist from GTA V. Now picture that as a 2D GBC game. That's pretty much what it looks like. You even jump a freight ship at the end of the level! But that's the only "cool" part.
